I thought the idea was that yeah you can use 68040 and 68060 sockets the recommended idea was to use the SIL strips and make up your own socket. Sort of like what Castellen or Anthony Hoffman suggests for the Cyberstorm MK-III 68060 socket repair:
http://amiga.serveftp.net/Cyberstorm_socket.html I'm probably misunderstanding but I thought there were two reasons for this, aren't we supposed to not connect up certain pins between the 060 board and the 040 board? Also since we need to put SIL pins in the top and bottom board to mate together and if you put an 040 socket on the lower board you still probably need the SIL socket since the 040 socket pins aren't necessarily going to be long enough to go through the lower board and into the 040 socket of the A3640/Warpengine/whatever. I figure it's going to be at least a week till my boards show up so I haven't gone through the fine details of what all I need yet. Tried looking for a ZIF 060 socket anyway, they say they exist but haven't found one yet.
